Jay Wilsey, aka Buffalo Bill Jr in westerns, wears overalls instead of Levis and has a throttle, rather than a horse's reins, in his hands but still ends up riding to the rescue, albeit on a faster track and a straighter line than usual.He is a straight-arrow railroad locomotive engineer who, when Matthew Betz stirs up the employees and leads a strike against the company, refuses to join the revolt, and scabs on down the line. This upsets Betz no end.William V. Mong, the railroad president, decides to disguise himself as an itinerant locomotive-fireman and go mingle amongst the workers and see what is causing all this unrest. By and by, Betz, and co-villain Walter Perry, get wise and clunk old Mong on the head and throw him into an empty locomotive, set it on a full-steam-ahead course which does not bode well for Mong or the locomotive.
